LONDON — Britons sometimes make fun of the French for feasting on frog. But now a new discovery suggests their prehistoric ancestors may have had a taste for toad.

The University of Buckingham said Wednesday that a promising excavation near Stonehenge has unearthed a host of clues about the diet of prehistoric Britons. Among them: A tiny, partially burnt leg bone which suggests the hunter-gatherers living in what's now known as the United Kingdom snacked on amphibians.
